Abstract

A power management circuit for logic cells. A logic cell is operated in normal or standby modes according to a power control signal. The logic cell includes an output terminal and a power input terminal. A switch is coupled between a power voltage, the power control signal and the power input terminal. That switch is turned off to disconnect the power voltage and the logic cell when the power control signal is at a predetermined level. This results in the logic cell operating in standby mode. A latch circuit is coupled between the power voltage and the output terminal to preserve the voltage level of the output terminal when the logic cell operates in standby mode.
